A taxonomy of behaviour change methods: an Intervention Mapping approach.

In this paper, we introduce the Intervention Mapping (IM) taxonomy of behaviour change methods and its potential to be developed into a coding taxonomy. That is, although IM and its taxonomy of behaviour change methods are not in fact new, because IM was originally developed as a tool for intervention development, this potential was not immediately apparent. Second, in explaining the IM taxonomy and defining the relevant constructs, we call attention to the existence of parameters for effectiveness of methods, and explicate the related distinction between theory-based methods and practical applications and the probability that poor translation of methods may lead to erroneous conclusions as to method-effectiveness. Third, we recommend a minimal set of intervention characteristics that may be reported when intervention descriptions and evaluations are published. Specifying these characteristics can greatly enhance the quality of our meta-analyses and other literature syntheses. In conclusion, the dynamics of behaviour change are such that any taxonomy of methods of behaviour change needs to acknowledge the importance of, and provide instruments for dealing with, three conditions for effectiveness for behaviour change methods. For a behaviour change method to be effective: (1) it must target a determinant that predicts behaviour; (2) it must be able to change that determinant; (3) it must be translated into a practical application in a way that preserves the parameters for effectiveness and fits with the target population, culture, and context. Thus, taxonomies of methods of behaviour change must distinguish the specific determinants that are targeted, practical, specific applications, and the theory-based methods they embody. In addition, taxonomies should acknowledge that the lists of behaviour change methods will be used by, and should be used by, intervention developers. Ideally, the taxonomy should be readily usable for this goal; but alternatively, it should be clear how the information in the taxonomy can be used in practice. The IM taxonomy satisfies these requirements, and it would be beneficial if other taxonomies would be extended to also meet these needs.

Finding theory- and evidence-based alternatives to fear appeals: Intervention Mapping.

Fear arousal-vividly showing people the negative health consequences of life-endangering behaviors-is popular as a method to raise awareness of risk behaviors and to change them into health-promoting behaviors. However, most data suggest that, under conditions of low efficacy, the resulting reaction will be defensive. Instead of applying fear appeals, health promoters should identify effective alternatives to fear arousal by carefully developing theory- and evidence-based programs. The Intervention Mapping (IM) protocol helps program planners to optimize chances for effectiveness. IM describes the intervention development process in six steps: (1) assessing the problem and community capacities, (2) specifying program objectives, (3) selecting theory-based intervention methods and practical applications, (4) designing and organizing the program, (5) planning, adoption, and implementation, and (6) developing an evaluation plan. Authors who used IM indicated that it helped in bringing the development of interventions to a higher level.

Safer choices 2: rationale, design issues, and baseline results in evaluating school-based health promotion for alternative school students.

BACKGROUND: Students attending 'alternative' high schools form relatively small, highly mobile high-risk populations, presenting challenges for the design and implementation of HIV-, other STI-, and pregnancy-prevention interventions. This paper describes the rationale, study design, and baseline results for the Safer Choices 2 program. STUDY DESIGN: Modified group-randomized intervention trial with cross-over of schools but not of students. The study cohort was defined a priori as those who completed the baseline measures and were still enrolled at the time of first follow-up. DESIGN RESULTS: Of 940 students initially enrolled in the study, 711 (76%) formed the study cohort. There were significant demographic differences between those included and those excluded from the study cohort in sex, age, sexual experience, experience with pregnancy, drug use, and some psychosocial measures. There were no significant differences between the intervention and control groups within the study cohort. The only significant difference between those students excluded from the intervention group and those excluded from the control group was reported age at first intercourse. BASELINE DATA RESULTS: Students (n=940) enrolled were predominately African-American (29.7%) and Hispanic (61.3%); 57.3% were female; 66% had ever had sex; and reported drug use in the previous 30 days ran from 4.3% (cocaine) to 26.9% (marijuana). Of the 627 sexually experienced, 41.8% reported their age at first intercourse as 13 years or younger; 28.5% reported ever being or having gotten someone pregnant; 74% reported sex in the past 3 months. Of the 464 sexually active in the last 3 months, 55.4% reported unprotected intercourse and 31.3% reported using drugs beforehand. CONCLUSION: The cross-over design will provide a rigorous test of the intervention; however, loss to follow-up of this population can result in some selection bias. Students attending dropout prevention and recovery schools are at high risk for HIV, STIs, and pregnancy, and are in need of interventions.

Effects of a preschool staff intervention on children's sun protection: outcomes of sun protection is fun!

The preschool is an important yet understudied setting for sun-protection interventions. This study evaluates the effects of Sun Protection is Fun! (SPF) on preschool staff behavioral and psychosocial outcomes related to protecting children from sun exposure. Twenty preschools participated in a 2-year, group-randomized trial to evaluate SPF, a behavioral intervention grounded in social cognitive theory and designed to be more extensive than previous preschool sun-protection interventions. The staff intervention included training, a video, newsletters, a curriculum, and sunscreen. Cross-sectional samples of staff completed surveys at baseline (N= 245), a 12 month intervention assessment (N = 192), and a 24-month intervention assessment (N = 225). At the 12-month and 24-month assessments, significant behavioral effects were seen for use of sunscreen, protective clothing, and shade. Knowledge, self-efficacy, and norms were among the psychosocial variables most affected by the intervention. This study demonstrates that the SPF intervention is effective in improving staff outcomes related to children's sun protection.

Asthma management simulation for children: translating theory, methods, and strategies to effect behavior change.

Translating behavioral theories, models, and strategies to guide the development and structure of computer-based health applications is well recognized, although a continued challenge for program developers. A stepped approach to translate behavioral theory in the design of simulations to teach chronic disease management to children is described. This includes the translation steps to: 1) define target behaviors and their determinants, 2) identify theoretical methods to optimize behavioral change, and 3) choose educational strategies to effectively apply these methods and combine these into a cohesive computer-based simulation for health education. Asthma is used to exemplify a chronic health management problem and a computer-based asthma management simulation (Watch, Discover, Think and Act) that has been evaluated and shown to effect asthma self-management in children is used to exemplify the application of theory to practice. Impact and outcome evaluation studies have indicated the effectiveness of these steps in providing increased rigor and accountability, suggesting their utility for educators and developers seeking to apply simulations to enhance self-management behaviors in patients.

Using intervention mapping to adapt an effective HIV, sexually transmitted disease, and pregnancy prevention program for high-risk minority youth.

Although many programs have been developed to reduce adolescent pregnancy and sexually transmitted diseases (STDs) (including HIV), with some showing promise in reducing sexual risk-taking behavior, little guidance has been given as to how to adapt existing interventions to new communities. When adapting a program, effective elements deemed necessary to change behaviors need to be preserved, while cultural competence and relevance for the new population must be considered in creating new elements. To address these needs, the authors describe the application of a systematic process, intervention mapping (IM), to adapt a theory-based, multicomponent HIV, STD, and pregnancy prevention program titled Safer Choices to a new target population, at-risk youth attending alternative schools and at risk of dropping out. IM is a detailed process that provides planners with a systematic method for decision making in each phase of developing or adapting an intervention to influence changes in behavior and environmental conditions.

An intervention for parents to promote preschool children's sun protection: effects of Sun Protection is Fun!

BACKGROUND: Young children are an important focus of sun-protection efforts, but there has been relatively little study of sun-protection interventions developed for preschool-aged children and their parents. This paper reports on the evaluation of Sun Protection is Fun! (S.P.F.), designed to improve parents' practices and psychosocial outcomes related to protecting preschool children from sun exposure. METHODS: A group-randomized trial was conducted in 20 preschools to evaluate the S.P.F. parent intervention that included a video, newsletters, and handbooks. A separate, on-site intervention for preschool staff aimed to create a preschool climate that encouraged parents' sun protection for their children. Cross-sectional samples of parents completed surveys at baseline (n = 384), 12 months (n = 640), and 24 months (n = 694). RESULTS: S.P.F. demonstrated significant effects on parents' sun-avoidance strategies at 12 months (P < .05) and sunscreen use at 24 months (P < .05). There were significant intervention effects on parents' sun-protection knowledge (P < .001), perceived norms of teachers' sunscreen use (P < .001), sunscreen impediments (P < .05), and sunscreen expectancies (P < .05) at 12 months. Parents' perceived norms of teacher sunscreen use were significantly improved at 24 months (P < .001). CONCLUSIONS: More intense intervention strategies may need to complement take-home materials to result in greater effects on parents' sun protection for their children.

The "Safer Choices" intervention: its impact on the sexual behaviors of different subgroups of high school students.

PURPOSE: To measure the relative impact of a school-based human immunodeficiency virus (HIV)-, sexually transmitted disease (STD)-, and pregnancy-prevention intervention on sexual risk-taking behaviors of different subgroups of students. METHODS: Twenty schools were randomly assigned to receive Safer Choices or a standard knowledge-based HIV-education program. Safer Choices was designed to reduce unprotected sex by delaying initiation of sex, reducing its frequency, or increasing condom use. Its five components included: school organization, an intensive curriculum with staff development, peer resources and school environment, parent education, and school-community linkages. A total of 3869 9th-grade students were tracked for 31 months. Results are presented for initiation of sex, frequency of unprotected sex, number of unprotected sexual partners, condom use, and contraceptive use. These results are presented separately by gender, race/ethnicity, prior sexual experience, and prior sexual risk-taking. Statistical analyses included multilevel, repeated measures logistic and Poisson regression models. RESULTS: Safer Choices had one or more positive behavioral effects on all subgroups. On four outcomes that could be affected by condom use, it had a greater impact on males than on females. It had greater effects on Hispanics, including a delay in sexual activity, than on other racial/ethnic groups. Its greatest overall effect was an increase in condom use among students who had engaged in unprotected sex before the intervention. CONCLUSIONS: Safer Choices reduced one or more measures of sexual risk taking over 31 months among all groups of youth, and was especially effective with males, Hispanics, and youth who engaged in unprotected sex and thus were at higher risk for HIV, other STD infections and pregnancy.

Healthy passages. A multilevel, multimethod longitudinal study of adolescent health.

PURPOSE: To provide an overview of a multisite, long-term study that focuses on risk and protective factors, health behaviors (e.g., dietary practices, physical inactivity, tobacco use, and violent activity), and health outcomes (e.g., diabetes, obesity, and sexually transmitted diseases) for a fifth-grade cohort to be followed biennially from ages 10 to 20 years. METHODS: A two-stage probability sampling procedure was used to select 5250 fifth-grade students from schools in Birmingham AL, Houston TX, and Los Angeles CA to ensure a sufficient sample size of African Americans, Hispanics, and non-Hispanic whites, to support precise statistical inferences. Computer-assisted technology was used to collect data from children and their primary caregivers. Teachers and other school personnel responded to questionnaires, and observational procedures were used to obtain information about schools and neighborhoods. RESULTS: To exploit the multilevel, multimethod structure of the data, statistical models include latent-growth mixture modeling, multilevel modeling, time-series analysis, survival analysis, latent transition analysis, and structural equation modeling. Analyses focus both on the co-occurrence and predictors of growth trajectories for different health behaviors across time. CONCLUSIONS: By using a prospective research design and studying the predictors and time course of multiple health behaviors with a multilevel, multimethod assessment protocol, this research project could provide an empirical basis for effective social and educational policies and intervention programs that foster positive health and well-being during both adolescence and adulthood.

School-based health education programs can be maintained over time: results from the CATCH Institutionalization study.

BACKGROUND: Developing and evaluating interventions to influence students' opportunities for healthful choices has been a focus of school-based health promotion research; however, few studies have examined the sustainability of these programs and viability of continued organizational implementation. METHODS: The purpose of this study was to determine the maintenance of Child and Adolescent Trial for Cardiovascular Health (CATCH) school-level changes in former intervention (n = 56) and former comparison (n = 20) schools 5 years post-intervention. Twelve schools unexposed to CATCH were measured as controls. Macronutrient content of 5 days of school lunch menus, amount and type of physical education (PE) classes, and health instruction practices in the classroom were assessed. An institutionalization score for schools was developed, using program maintenance variables: % kcal from fat and saturated fat in school lunches, % PE class spent in vigorous and moderate-to-vigorous physical activity, and class time devoted to CATCH topics. RESULTS: Menus from 50% of former intervention cafeterias met the Eat Smart guidelines for fat, compared to 10% of former control cafeterias and 17% of unexposed school cafeterias (P < 0.005). There were no significant differences in implementation of CATCH PE goals between conditions. Although the total time spent teaching CATCH was low in former CATCH schools, the former intervention schools spent significantly more time teaching CATCH and taught more lessons as compared to former comparison schools. Former intervention schools had a higher mean institutionalization score than former comparison schools (P < 0.001). Training had the greatest impact on maintenance of CATCH. CONCLUSIONS: Results from this study suggest that changes in the school environment to support healthful behaviors can be maintained over time. Staff training is an important factor in achieving institutionalization of these programs.

Development of a cervical cancer educational program for Chinese women using intervention mapping.

This article describes the development of a program to increase Pap screening behavior among women in Taiwan. Intervention mapping, an innovative process of intervention design, guided the development of this program. The development process included a needs assessment identifying factors influencing Pap screening behavior relevant to Chinese women. The program used methods such as information transmission, modeling, persuasion, and facilitation. Strategies included direct mail communication, role-model stories and testimonials, and a telephone-counseling component. The delineation of specific plans for implementation and evaluation are also described.

Institutionalization of a school health promotion program: background and rationale of the CATCH-ON study.

Research is lacking on how to make effective programs available on a large scale and how to maintain levels of implementation. CATCH: A Study of Institutionalization (CATCH-ON) was designed to help us understand the conditions under which such programs are institutionalized after the trial has ended. The Child and Adolescent Trial for Cardiovascular Health (CATCH) was the largest field trial of school-based health promotion in the United States conducted in 96 schools in four geographic areas of the United States: California, Louisiana, Minnesota. and Texas. The intervention was multicomponent, targeting school policy and practices in nutrition, physical activity, health education, and smoking. This report provides background on the CATCH study design, the conceptual framework for research on institutionalization of the CATCH program, and an overview of the seven original reports that present results from the CATCH-ON study in this theme issue.

Maintenance of the classroom health education curricula: results from the CATCH-ON study.

Maintenance of the interactive Child and Adolescent Trial for Cardiovascular Health (CATCH) third- to fifth-grade curricula was studied in the 56 original intervention schools and 20 of the original control schools 5 years postintervention in four regions of the United States. Target grade teachers completed a self-administered survey that included questions regarding use of the CATCH materials, training in CATCH or other health education, barriers and perceived support for health education, and amount of health education currently taught. Percentage of teachers who continued to teach CATCH in the classroom was low; however, percentages were significantly higher in former intervention compared with control schools, even though control schools received training and materials following the main field trial. The results of this study can provide useful information for future development of classroom health promotion materials with a higher level of sustainability.

School climate and the institutionalization of the CATCH program.

School climate refers to various physical and psychosocial structures that shape schools' social and physical environments. The Child and Adolescent Trial for Cardiovascular Health (CATCH) study provided an opportunity to study how aspects of school climate are associated with continued implementation of the CATCH program. Nutrient analysis of menus, observations of physical education (PE) classes, and teacher and staff self-reports were used to measure CATCH program components. Results of this study indicate that aspects of school climate were associated with continued implementation of the CATCH classroom component but not the CATCH food service or PE components. These findings have implications for how we plan for the progression of innovative school health promotion programs from the initial trial stage to institutionalization. Measures of school climate may be useful in determining a school's readiness to adopt and implement an innovative health promotion curriculum.

Correlates of cervical cancer screening among women in Taiwan.

In this study we examine several theory-based psychosocial factors on cervical cancer screening among Chinese women in Taiwan (N = 125). The reliabilities of the scales showed good internal consistence (Chronbach alpha ranged from 0.68 to 0.88). We found that 30% of the women had never received a Papanicolaou (Pap) test, and only 58% reported a screening in the past 3 years (adherent). Intention to have a Pap test in the coming year was higher among screening adherence women (90%) than nonadherents (58%). Multiple logistic regression analysis revealed significant associations between screening adherence and women's knowledge (p = 0.034), perceived pros (p = 0.041), cons (p = 0.000), and norms (p = 0.019) of a Pap test. In addition to identifying screening associated factors, we also provided a basis for measuring important theory-based constructs. Although we developed some scale items for Chinese culture, data showed that psychosocial factors were universally relevant. Future intervention efforts tailoring these factors could potentially impact cancer screening for women internationally.

Family connectedness and sexual risk-taking among urban youth attending alternative high schools.

CONTEXT: Youth in alternative high schools engage in risky sexual behavior at higher rates than do their peers in regular schools, placing themselves at an increased risk of sexually transmitted disease and unintended pregnancy. Family connectedness is associated with reduced adolescent sexual risk-taking, although this association has not been tested among alternative school youth. METHODS: A sample of 976 urban, predominantly minority alternative high school students in Houston, Texas, were surveyed in 2000-2002. Survey data were analyzed using logistic regression to determine whether family connectedness is related to sexual risk-taking. RESULTS: Overall, 68% of students reported ever having had sex. Of sexually experienced students, 74% reported having had sex in the past three months and 29% reported ever having been involved in a pregnancy. The higher students scored on a scale of perceived family connectedness, the less likely they were to report ever having had sex, recently having had unprotected sex and having been involved in a pregnancy (odds ratio, 0.97 per unit increase for each outcome). Among females, higher perceived family connectedness was associated with reduced odds of ever having had sex or having initiated sex prior to age 13 (0.96 for each); males who perceived higher family connectedness had reduced odds of having been involved in a pregnancy (0.93). CONCLUSIONS: Family connectedness may be a protective factor related to sexual risk-taking, even among high-risk youth. Including activities that acknowledge the influence of family relationships and facilitate positive parent-child relationships may increase the efficacy of programs for reducing sexual risk-taking among alternative school youth.

Preparedness of health care practitioners to screen women for domestic violence in a border community.

Health care professionals do not always screen patients for domestic abuse. In the absence of screening, the likelihood of misdiagnoses and prescriptions contraindicated for symptoms of abuse survivors is increased. Several factors may contribute to the lack of routine and uniform screening, including a lack of educational preparedness. The qualitative findings presented here are part of a larger quantitative study investigating the skills, beliefs, and expectations about screening for domestic abuse among physicians, dentists, and nurse practitioners from a border community in southwest Texas. Practitioners requested specific information to enhance educational preparedness and improve clinical practice for their abused patients.

Validity and reliability of the parental sun protection scales.

Skin cancer is the most common cancer diagnosed in the US and its incidence continues to rise. Epidemiological studies have shown that excessive sun exposure received during childhood may increase the risk of developing skin cancer later in life. Yet, there are few published reports on the development of reliable and valid theory-based scales that assess the factors associated with parental sun-protection practices to reduce sun exposure in preschool children. To fill this gap, the Parental Sun Protection Scales were developed and validated. Two series of confirmatory factor analytic models were employed to test the factor structure of the scales and to examine the inter-relationships among the proposed psychosocial factors. Sunscreen-use and sun-avoidance behavioral models were tested in a sample of 384 parents. The results provided a basis for the reliable and valid measurement of psychosocial factors related to parental sun-protection practices. These scales may be useful in more fully understanding the determinants of sun-protection behaviors and in evaluating intervention programs designed to improve such behaviors.

Effectiveness of an intervention to increase Pap test screening among Chinese women in Taiwan.

This study assessed the effectiveness of a theory-based direct mail campaign in encouraging non-compliant women, aged 30 and older or younger if married, to obtain a Pap test. Participants were female family members of inpatients admitted to one of the major teaching hospitals in Taiwan during August-September 1999. A total of 424 women were recruited in the randomized intervention trial. Three months following implementation of the intervention, women in the intervention group reported a higher rate of Pap test screening than women in the comparison group (50% versus 32%) (p = 0.002). Women in the intervention group also showed higher perceived pros of a Pap test at follow-up (p = 0.031). Although women in both groups showed an increased knowledge and intention to obtain a Pap, only the intervention group had significantly higher follow-up scores on perceived pros and susceptibility. The results shows that the intervention was effective in increasing Pap test screening among Chinese women within three months. The results also support the use of Intervention Mapping, a systematic program development framework for planning effective interventions.
